  • the invention is based on the judicious recognition that other shapes of concrete external shell than the traditional cylindrical design, will enable building much larger LNG storage tanks than assumed thus far.

  • said walls being concentric relative to each other.
  • said walls are annular.
  • membrane technology refers to a membrane-type internal containment system that generally comprises a laminate of a plurality of barrier layers and insulating layers. Generally one or more layers of a barrier material are put on the LNG- containment side and within the insulating layers.
  • the insulating layers generally comprise a multilayer structure, e.g. a laminate comprising stainless steel, and one or more insulating layers, generally in the form of panels.

  • the insulating panel is anchored to a concrete wall, by anchoring elements such as mastic and studs.
  • secondary barrier is e.g. a composite material comprising an aluminum sheet inserted between two layers of woven fiber glass.
  • LNG Insulating Membrane generally refers to a multilayer structure comprising a metal layer that is to form the inside (i.e. the LNG containment side) of a storage tank, an insulating layer placed on the outside (i.e. facing in the opposite direction from the LNG containment) of the metal layer, and a second metal or composite layer placed on the outside of or within the insulating layer, thus forming a laminate of several consecutive layers: metal - plywood - insulation - secondary barrier - insulation - plywood -.
  • Other configurations than this sandwich multilayer including different orders of layers and larger numbers of layers, are conceivable.
  • the multilayer structure in an LNG membrane generally refers to layers that are connected, but which are capable of movement relative to each other.
  • a preferred LNG Insulating Membrane comprises primary and secondary membranes both made from Invar (a 36% nickel-steel alloy).
  • the invention provides an at least bifold recognition. On the one hand, that LNG Insulating Membranes do not bring about limitations as to size. Thus, this technology can be used in accordance with the invention to provide LNG storage tanks, on shore, of larger size than have existed. On the other hand, the invention provides the acknowledgement that the size limitations of cupola structures in concrete can be avoided for LNG storage tanks.
  • the invention provides a shape for the concrete housing that is, in its simplest form, a floor representing a rectangular plane, provided with four walls, each defining a side of said plane, and a roof covering said walls.

  • the ability to construct a roof of limited span is given by the limited span provided by the limited width of this
  • the longitudinal walls need not be parallel to each other. In that case the transversal walls will simply have different lengths.
  • the walls can extend perpendicular to the floor, but it is also conceivable that one or more of the walls are tilted, i.e. making an angle different from 90° with the floor.
  • the LNG storage tank of the invention can have a number of walls different from four.
  • an angular structure can be built having more than four walls.
  • the ground plane has an L-shape, an H-shape, a U-shape, or any other shape in which a three- dimensional volume can be realized in concrete, without the limitations associated with a concrete roof that needs to span a cylinder as is currently done in the art.
  • the at least two walls can refer to a single wall in which, other than in the case of a cylindrical structure, at least two different segments of the wall can be distinguished.
  • Such different segments can, e.g. be, two substantially parallel segments, or they can be the different segments (longitudinal and transversal) recognized in an ellipse.
  • the at least two walls can be in the form of segments of a single wall having a semi-circular or elliptical shape.
  • the walls are concentric vis-a-vis each other, and more preferably annular. I.e., here only two walls are required. It is conceivable to extend the concentric design with one or more further walls, i.e. viewed from the top these represent a plurality of concentric circles.
  • a technical advantage of an annular tank design is that, in a better way than in the even of designs with angles, such as a parallelepipedic design, the design of the invention combines the advantages of the possibility to design a larger volume than for a cylindrical tank, with the advantage of a cylindrical tank that stress distributions can be well predicted (better than in the event of angular walls).
  • the LNG storage tank of the invention can be placed above ground, but can also be realized with an embankment, or semi-buried.
  • the annular design is preferred, as this shape will be better capable of bearing the soil pressure.
  • the material, in which the concrete housing is built, is pre-stressed concrete. It is well-known to the skilled person in building LNG storage tanks how to provide concrete suitable for building LNG storage tanks, and how to build the tanks.
  • the designs according to the invention represent shapes that a skilled person can easily build in pre-stressed concrete.
  • the LNG storage tank of the invention comprises a closed compartment
  • this refers to a compartment capable of containment of LNG. This does not exclude the presence of any valves, doors, or other facilities that may result in the closed compartment to be opened.
  • the roof can have any shape, e.g. a flat roof, a gabled roof, a hip roof, an arched roof, which are all shapes that by mere lengthening of the longitudinal dimension of the housing can support a larger volume than a domical roof (i.e. a cupola).

  • Both of these examples can be built with a height similar to that of conventional storage tanks, which is typically 30 to 50 meters.
  • the LNG storage tanks of the invention further comprise those facilities that are known in the art as required for LNG storage.
  • the tanks will have, several LNG- and utilities-connections with external networks and internal pumps for pumping LNG out of the tank.
  • the invention brings about further advantages.
  • the aforementioned height is reduced by the bottom minimum level and top margin to give, for instance, for a wall height of 37 meters a working height of LNG of about 30 meters.
  • a larger working height can be obtained in several ways.
  • One is related to columns that are normally present to accommodate internal pumps in the storage tank. By placing the bottom of this column in an insulated pit, some 2 to 2.5 meters height of the pumps suction head can be saved. This is allowed by the fact no displacement of the pit will result from thermal contraction of the membrane tank liner, contrary to a bottom comprising 9% Ni steel plates.
  • a preferred embodiment provides for installing the normally internal pumps outside of the tank, in the confined internal concrete cylindrical wall, and to feed them by piping branched through bottom of the cryogenic containment. This is allowed because, in this case, any leak will be confined in this internal wall.
  • the external pumps could be direct HP (High Pressure) pumps, thus avoiding a two stages pumping (LP in-tank pumps + external HP pumps).
  • a major advantage is that the new designs require much less space and limit the number of internal equipments (pumps, instrumentation) and network connections, to two sets instead of 9.
  • the invention pertains to concrete structures some of which may have existed before in buildings for different purposes.
  • the presence of an LNG-tight lining, the inlet and outlet, and one or more pumps readily distinguishes the concrete housing of the invention from edifices for other purposes.
  • the invention relates to a concrete, membrane technology -lined tank as described hereinbefore, containing LNG.
  • the invention puts to use an LNG membrane technology (membrane technology as known in the field of LNG storage), for building on-shore concrete LNG storage facilities of increased capacity.
  • the invention puts to use a concrete structure of the type described hereinbefore, for the storage of LNG.

Abstract

L'invention concerne un réservoir en béton destiné à des réservoirs de GNL de très grande dimension. L'invention utilise la technologie des membranes dans des structures en béton qui diffèrent des constructions cylindriques classiques. Les enceintes en béton caractéristiques de l'invention présentent une structure parallélépipédique ou une structure annulaire comprenant deux parois concentriques. Les deux structures peuvent être recouvertes d'un toit en cloche ou en arc de cercle et permettent d'éviter les restrictions en termes de dimension imposées aux structures cylindriques en conséquence des restrictions en termes de dimension inhérentes aux dômes en béton. L'invention concerne également plusieurs moyens permettant d'améliorer la hauteur de travail disponible pour le GNL à l'intérieur de structures en béton de ce type d'une hauteur donnée.
